Briefly describe the temperature and precipitation conditions required to sustain the deciduous forests of
western Europe.

The average temperature of deciduous forests is 50°F and annual rainfall averages 30 to 60 inches. Temperate deciduous forests also have precipitation in the form of snow. Deciduous forests must have at least 120 days without frost. This period can extend to 250 days in some tropical and subtropical deciduous forests. Tropical and subtropical deciduous forests have a very tight temperature range between 68°F to 77°F.

Explanation:

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
